At least under SunOs and Ultrix there is a programm called "line"
which does the job. You'll like to read the man page.

	fn read {
		$1=`{ line }
	}

I think that in general you will run into trouble with utilities that
buffer their input. Therefore you'll need to write a C program that
reads 1 character at a time up to a newline, then quits.

Please someone tell me I'm wrong.

Hmm, I agree that `{sed 1q} seems to read one too many lines.
This works okay for me, don't know about elsewhere:
	`{head -1}

is there any clever way to do 'read' in rc scripts?

[Chris Siebenmann]

 I've recently run into a situation where I really, really could use
an rc equivalent of the sh read command in a script, and I can't figure
out how to do this. Any number of methods will work ... if you're getting
input from the keyboard. At least on Ultrix, all of them gobble some or
all of the remaining input if invoked on a pipe or a file.

 Any clever ideas, anyone?
